Rumbling Bridge is a tiny village in Kinross-shire, Scotland, nestling under the Ochil Hills, where the A823 leaves the A977, perched on the edge of the River Devon gorge. It lies between Muckhart and Crook of Devon with Powmill half a mile to its south. It is named after an unusual double (arguably treble) bridge, which gives off a distinctive rumbling reverberation at lower levels. Most property in the village dates from the last 20 years.
The "lower" bridge, without parapets, was built in 1713 by William Gray, a mason from Saline. It is 22 feet long and 11 feet wide and 86 feet above the average water level. However, an ancient bridge preceded this and is still (just) visible. It takes the form of a single large stone slab over the river at the very base of the gorge, so serves no advantage to vehicles, and was simply a means of crossing for pedestrians without getting their feet wet.
The second bridge or Upper Arch (120 feet above the river) was constructed 34 feet above it in 1816 and "gave it an easier gradient" by removing the steep slope down to the old bridge. 1816 was a dramatic year as ... 1816. "On 18 March, happened the greatest flood ever heard of or seen in Kinross; all the burns were brimfull;" and later "On 13 August a smart shock of earthquake was felt throughout Kinross at 11 o'clock at night. Plates rattled on shelves; chairs moved about and were thrown over; beds shook, &c." There was also a "wet and late harvest" during which there was snow on four different occasions from five to six inches deep.'
Unlike the Rumbling Bridge over the River Braan near Dunkeld, the River Devon cannot be canoed. There is a good, well maintained path round the upper gorge built by the armed forces. About 350 yards above the bridges is the Devil's Mill waterfall. At the Devil's Mill, "the river, after running in a rocky channel with a rapid descent, enters a deep basin formed in the rock ; from this basin it descends into a cavity below, where the water is whirled about with great violence, and, constantly beating against the sides of the rock, produces a sound" like that made by the machinery of a mill in motion. It is best seen from the south bank."
